LulzSec hacker helps FBI stop over 300 cyber attacks

http://www.bbc.com/news/technology-27579765The former "leader" of hacking group LulzSec has helped the FBI stop more than 300 cyber attacks since his arrest on hacking charges in 2011.

The co-operation of Hector Xavier Monsegur has helped to prevent losses of millions of dollars, according to court documents filed by prosecutors.

Mr Monsegur will be sentenced on Tuesday for his role in major online hacking attacks.

Prosecutors have recommended that he receives a reduced sentence.

LulzSec was formed in approximately May 2011 when Mr Monsegur - also known as Sabu - and five other members of the Anonymous hacking movement joined forces.

According to the documents filed with the court the group was responsible for "major hacks" into and "thefts" from computer servers belonging to companies including Fox Television, Nintendo and Sony.

Mr Monsegur was arrested in June 2011 and pleaded guilty, as part of a co-operation agreement with the US government, to nine counts related to computer hacking, amongst others.

'Extraordinarily valuable'
The documents that were filed in a New York court last week state that Mr Monsegur's most substantial assistance came from his "co-operation against significant cybercriminals" affiliated with Anonymous, LulzSec and Internet Feds - another hacking group.
